more uniformly than pokers heretofore used.

Further the invention aims to mount and operate 'the poker ii 'such a.way that therey is a slicin orplowing action and a slight packinge ectwithout causing thepoint or lower end of the poker to `haveexcessivedifferences in level in the-fuel bed.

A further object is to provide a construction such that the pokermechanism can be water sealed and thus made absolutely gas tight.

The poker most generally used heretofore,

i knownas the Hughes poker, is mounted on 'trunnions, and the pokerproper is oscillated or swung back and forth through an arc of a vcirclelying in a vertical plane. The oscillatorymovement is a ve desirableone,

' and the present poker mec anism-is preferably such that an oscillatorymovement is utilized but the movement of the poker is other than in avertical plane. Preferably the poker is mounted and oscillatedv in sucha manner that the point of the poker travels back and forth in an arc ofa circle lying in a plane which is nearer the horizontal than thevertical, but inclined with respect to both so that as the poker isswung back and forth, toward the wall of the producer body and thentoward the center or axis of the roducer body, it will thoroughly overthe ofthe producer arerotated relatively, and at the same time the pointof the poker will be slightly lower when the poker is in' its extremepositions than .in the mid osition thus producing the desirable packingeffect. v Y i.

The invention may be further briefly summarized as consisting in certainnovel details of construction, and combinations and arran ements ofpartswhich will be describedvin the speciiication and set :forth in theappendedc aims.

In the accompanying sheets of drawings, Fig. 1 is a vertical sectionalview throu h a producer equipped with thepoker mec anism embodyin the.present invention;

" 2 is a top p an view of the same; Fig.

3 is an enlarged vertical sectional view taken at substantially rightangles to the section ed of fuel as the body and coverv poker by willyof bolts 26 to Renewed February as, was.

vof Fig.. 1; and Figs..4, 5 and 6v are Sectional .views substantiallyalong the line -B of Fig. 3, with the poker in -its two 10 and 11 isrotated relatively tothe other,

and in this instance the cover is stationary and the producer body isrotated, the body being supported on rollers, one of which is shownlat12 engaging a track 13 surrounding the producer body. The producer bodymaybe rotated-by any suitable mechanism, but ini this instance it issurrounded by a gear 14 which is engaged Aby and rotated by a pinion l5on a .vertical shaft 16 alongside the producer body. .l

The top of the producerbody and the peripheral` ortion of the cover arewatersealed int e customary manner as shown 'at drawings, 10 repi 17.Additionally any suitable charging apable way as by means 'of a i e orconduit 18. p P

The poker '19 with which the resentiini vention is involved, is preferabfrom end, to end, and. asy here cludes a main hollow bod a removable tip20 at its lo y straight shown, in-

wer end, and

with a cap 21 at its upper orouter end. The

Esker is preferably water-cooled, the water ing conducted down tothe'lower end or tip of the poker by a pipe y22and, being conducted romthe bodyv portion of ,the

chars into the cover, and from which there one or more overiow voutletstothe trough of the main water seal at the top of the producer body.

a dischargefpipe 23 which disportion with' The upper part of the pokerAis seatedv l and fixed in `a suitably formedsocket of an oscillatoryhead 2,4, though the oker can be readily removed from the hea -byslipping it in an endwise 4direction out from', for repairs and thelike.. The head 24 ,is journaled in 'a cylindrical normally fixed'bearing 25 which likewise can be removed but is there-v normally securedby a series an annular or lsubstantially annular upstanding seat 27 ofthe producer 4cover 11.

from the cover. This ange is surrounded by a` larger and somewhatsimilarly shaped depending flange 30 on the head 24 carrying the poker.inasmuch as the shape of; the cover, clearly shown in Fig. '3, is'vsuchas to provide a depression around the flange 29, it is apparent that avery effective water sealis thus provided, and that gas will not escapefrom the producer around the poker.

It is to be noted, particularly by reference v to Fig. 3, that the pokeris set into the oscillatory -head 24 at an angle to the latters axis sothat when the head is oscillated, the point of the poker will swingthrough an lare of a circle in a plane normal to the axis of the head24. It will be noted also, that the axis of the head, 'and likewise theaxis of the'bearing 25 are inclined to the vertical or to the axis ofthe producer, that is, the axis about which the head 24 turns lies in aplane other. than the horizontal. By reason of this novel constructionand arrangementnet-onl will the point of the poker swing throug the arcof a circle when the head. is oscillated, but the plane containingthearc of the circle being normal to the inclined axis of lthe head isinclined both tothe horizontal and the vertical, the inclination withrespect to the l horizontal being equal lto the inclination of theoscillatory head with.respect to the vertical.

By reference to Figs. 1, 2 and 3 it will be observed that the point ofthe poker swings as the through an arm of a circle extending Arom apoint near the producer axis to a point near the upright wall of theproducer body. As the pokeris oscillated in this fashion at rthe sametime that the producer body and bed of fuel are rotated in the directionindicated by the arrow of Fig. 2, it is obvious that the fuel bed willbe very completely covered by the cker, a slicing or plowing actionbeing obtained due to the inclination of the poker. In this-respect thepresent invention is an improvement over poker mechanisms heretoforecontemplated wherein the poker is given a complete rotation about avertical axis.

Likewise it 'will be noted that inasmuch plane of movementof the pointof the poker 1s inclined to the horizontal and the oint of the pokeroscillates through anarc 1n the upper portion of a circle in said plane,

the point of the poker will be slightly deeper ,when at the limits ofits movement rather "than at anyY intermediate point, so that as 'thepoker is oscillated, the plowing or slicing a maximum'degree theadvantages of prior constructions, and possesses to aminimum extenttheir disadvantages.

The poker may be oscillated in dierent ways, but in this instance theshaft 16 which rotates the producer body is provided at its upper endwith a pinion 31 which meshes with, and rotates a gear 32 having a crankpinv 3-3 connected by a connecting rod 34 to a crank arm 35 extendinglaterally from the poker head 24. rlhe pinion 31 and gear 32 areslightly beveled, and the gear 32 is set at an angle with reference tothe axis of the pinion 31, which angle corresponds to the inclination ofthe poker head 24 in its bearing 25, in consequence 'of which the gear32, connecting rod 34 and crank arm 35 lie in the same plane, andfreedom of movement is obtained. I Y

Modications may, of course, be-made not onlyin the construction of thepoker mechanism, but in the degree of movement which is imparted to thepoker proper. For a poker designed to have the extent of arcuatemovement illustrated, a water seal flange 29 of the shape Iillustratedin Figs. 4, 5 and 6 may be employed, but ifl the poker he given agreater arcuate movement than that contemplated byfthe present design,the inner water seal flange 29, and, of course, also the outer waterseal flange 30 will be-shaped so as to permit the full movement desired.
